Purpose: Suicide attempts are known to be influenced by mass media reports. The purpose of this study was to evaluate the effects of mass media reporting celebrity suicides on an increase of intentional carbon monoxide (CO) poisoning and suicide attempts. Methods: We retrospectively reviewed the medical records of the consecutive patients who presented with suicide attempts to the Emergency Department of Ajou University Hospital during a 24 month period. We obtained the demographic data, any past history of suicide attempt and the methods of suicide attempts from the medical records of the suicide attempters. Time series analysis was conducted for evaluating the influence of mass media reporting of celebrity suicide on the suicide rates. Results: We finally enrolled 770 patients during the study period. The total number of suicide attempts by CO poisoning was 18 and the average number of suicide attempts by CO was $0.33{\pm}0.73$ per week. All of the suicide attempts by CO poisoning occurred after a celebrity committed suicide using CO from burning charcoal. Conclusion: This study showed that celebrity suicide by CO poisoning resulted in the Werther effect, which made the rate of intended CO poisoning increase, and the study provided further evidence for the need to actively restrain mass media reporting of suicide to decrease the Werther effect.

Purpose: The purpose of this study was to identify the effect of parent-adolescent communication and depression on suicide ideation in the adolescent population. Method: The participants for this study were 391 students from two middle schools, one located in Seoul and one in Kyung-gi do Province. A self-report survey was used for data collection, which was carried out from February 8 to 14, 2006. The collected data were analyzed using SPSS 11.0 Program. Results: The average score for father-adolescent communication was 61.70, and for mother-adolescent communication, 64.04. The average score for depression was 16.01, and for suicide ideation, 8.69. There was a statistically significant positive correlation between suicide ideation and depression. There was a statistically significant reverse correlation between suicide ideation and mother-adolescent communication, and between suicide ideation and father-adolescent communication. Mother-adolescent communication and depression account for 46.4% of variance in suicide ideation of adolescents. Conclusion: According to the results, programs designed to improve parent-adolescent communication and decrease depression should be developed and put into practice to decrease the rate of suicide ideation in adolescents in Korea.

Purpose: This study was conducted to analyze the social factors influencing the 'authenticity of suicidal ideation' based post-suicidal care programs in emergency departments (EDs). Methods: This retrospective study was an analysis using the data of patients who had attempted suicide and visited the ED in tertiary urban hospitals from January 1, 2016, to December 31, 2018. The variables examined included gender, age, history of previous psychiatric disease, suicide method, and the number of previous attempts. Univariate and multivariate logistic regression analyses were conducted to identify factors influencing the registration rate for the community-based post-suicide care program. Results: Overall,1,460 suicides were analyzed, 177 (1.16%) showed a high authenticity of suicide. The social factors influencing the authenticity of suicide intent were the unmarried status of men and women, joblessness, history of mental illnesses, more than two previous suicide attempts, the influence of alcohol, and an attempt to commit suicide after midnight more specifically between 24:00 to 6:00 hours in the morning (p<.05). The factors influencing the severity of the condition of high authenticity suicide patients were low Glasgow coma scores (12 points or less), lactate levels, and oxygen saturation observed in the patients who were admitted to the intensive care unit for treatment and died (p<.05). Conclusion: The need for evidence-based preventive measures and early assessment tools at the emergency medicine level is emphasized to reduce the rate of suicide attempts. If the results of this study are used in the management of suicide prevention, the evaluation of the authenticity of suicide intent will be more likely to be made at the emergency medicine level, allowing the severity to be assessed earlier.

Objectives There were previous studies which indicated that attitude toward suicide is able to influence the suicide outcome in both individual and group levels. In regard to the highest suicide rate in Korea, our study aims to explore the influence that attitude toward suicide has on suicide by comparing the national attitude towards suicide with a representative sample of the general population. Methods The target population was 20- to 59-year-old adults from South Korea, Japan, and the United States. The panel data were divided according to gender, age, and residential area of individuals, and an email with a hyperlink to our web survey was sent to the randomly selected participants in each stratum. To measure the perceptual differences about suicide in different cultures, this study adopted the Attitudes Toward Suicide questionnaire. Results A total of 2247 subjects in three countries participated in this study. According to results from factor analysis, there were different structure of factors and included items within factors in the three countries : five factors with nineteen items in South Korea, five factors with nineteen items in the United States, and five factors with twenty-five items in Japan. With regard to permissive attitude toward suicide, the mean value of permissiveness was not significantly different among countries, but permissiveness according to education level, gender, and marital status was different in each country. Conclusions This study is the first nationwide comparative study about attitude toward suicide with a representative sample. Our findings suggest that permissive attitude toward suicide influence the suicide phenomenon in each country ; however, its impact is not a mean score of permissiveness, but the detailed difference by various demographics.

Objectives: Rural-urban differences in suicide have been observed in many settings. However, there has been little research addressing what factors can explain these differences. The purpose of this study was to analyze which compositional factors and contextual factors in local areas might be related to local suicide. Methods: The study design was cross-sectional. The data for 251 primary local governments on their age-standardized suicide mortality and their predefined indicators of compositional factors and contextual factors were obtained from Korean Statistical Information Service as of year 2010. Bivariate analysis including one-way ANOVA and chi-square test were used to identify the differences in local features by area type. Seven poisson regression models for each of total, males, and females were used to analyze which compositional and contextual factors were related to suicide. Results: There were differences in suicide between gu and goon in total, male, and female groups. For total, compositional factors including divorce and smoking rate, and contextual factors including financial independency, water and waterwaste coverage, and number of wastewater discharge factories were found to explain the urban-rural differences. Conclusions: This study provided some evidence that contextual factors at the local level as well as compositional factors are useful for predicting local suicide mortality.

Objectives: This study investigated the relationship between oral health and suicide attempts in adults aged 19 years or older using the 7^th Korea National Health and Examination Survey (KHANES, 2016-2018). Methods: Of the 24,269 participants in the 7^th KHANES (2016-2018), 7,261 adults aged 19 years or older who had an oral health examination were selected. Complex samples crosstabulation (χ²-test) was performed to determine the rate of suicide ideation by general characteristics. Complex samples logistic regression was performed to ascertain the effects of oral health on suicide attempts. Results: Participants with gingivitis were 1.7 times more likely to receive mental health counseling (p<0.05) and 1.6 times more likely to attempt suicide (p<0.05). Conclusions: Oral health is significantly associated with suicide attempts in adults aged 19 years or older, and this emphasizes the importance of oral health management as an intervention for preventing suicide and improving the health of adults.

오늘날 우리는 자살사례를 쉽게 접할 수 있으며, 한국 사회에서 자살은 중요한 사회문제로 대두되었다. 우리나라의 자살 추세를 살펴보면, 연간 자살자수는 1990년 3,157명에서 2006년 10,688명에 이르기까지 지속적인 증가세를 보였다. 이는 하루에 29명, 50분마다 한명 꼴로 자살하는 것이다. 인구 10만명 당 자살률은 1991년 9.1명에서 점진적으로 증가해오다가 1996년과 1997년에 각각 13.9명과 14.1명으로 소폭 상승하였으며, 외환위기를 맞은 1998년에 19.9명으로 대폭 상승하여 정점에 이르렀다. 그 이후 다시 감소하기 시작하여 2000년 14.6명과 2001년 15.5명을 기록하여 안정세를 되찾는듯하였으나, 다시 경기가 악화되기 시작하면서 2002년 19.1명, 2003년 24.1명, 2004년 25.2명, 2005년 26.1명으로 계속 증가하였다. 2006년에는 2000년 이후 6년만에 자살률이 감소되었지만 23.0명으로 여전히 높은 실정이다. 또한 우리나라의 자살은 10대 사망원인 중 2001년 8위에서 2002년 7위, 2003년 5위, 2004년과 2005년에는 4위로 그 순위가 계속 상승하였다. 2006년 기준으로 우리나라의 자살사망률은 경제협력개발기구(OECD) 회원국가 중 헝가리(22.6명)에 이어 2위를 기록했다. 이는 미국(10.2명), 영국(6.3명), 프랑스(15.3명) 등 주요국에 비해서 상당히 높은 수준이며, 자살왕국으로 불리던 일본(19.1명)에 비하여도 높게 나타났다.

Purpose: This study was conducted to investigate the independent factors associated with the registration rate for the community-based post suicidal care program in the emergency department (ED). Methods: This prospective observational study was conducted between January and September 2015 at the academic ED in the tertiary urban hospital. The variables examined included gender, age, address, type of insurance, history of previous psychiatric disease, suicide methods, number of previous attempts, CES-D (The Center for Epidemiologic Studies-Depression Scale), and disposition at ED. Univariate and multivariate logistic regression analysis were conducted to identify factors affecting the registration rate for the community-based post suicidal care program. Results: Overall, 331 suicides were investigated, 61 (18.4%) of which were registered in the post-suicide care program. Factors such as a intervention by psychiatric physician (OR: 3.287, 95%; CI: 1.207-9.624) and levels of depression by CES-D score of 16-24 (OR: 3.635; CI: 1.055-12.526) were significantly correlated with registration for the program. Conclusion: The registration rate for the community-based post suicidal care program was influenced by frequent intervention by a psychiatric physician and levels of depression by CES-D score of 16-24.
